@ colinbm,
I would have expected a range of 4 metres the most. If you are getting up to 12 metres that is a bonus. Thanks for the info on the torches.
The Jaycar unit works better than the remote doorbells I was using. Considering the electronic components inside; the Jaycar unit is a bargain. I was talking to the Jaycar sales guy about the units. They are a slow moving item. The impression I got was Jaycar are having trouble selling them.
I played around with the Jaycar unit on my desk. With the S3IS switched off; first press turns on the camera, second press zooms the lens, double press takes a photo. The double press is a bit tricky because of the remote membrane; it takes getting used to. I may have to look at extra electronics and automating the process.
PS. I just got logged off because of the time factor. If that happens, in Firefox, back page, highlight your text, copy, login again, paste into the box.
I just read the previous page on your S5IS problem. I set up CHDK a while ago, but only use the camera for basics; house renovations and no time to play with the toy.
I am a hardware guy, not software. Try the above sequence to take a photo. If the membrane is tricky try it with the cover off. The switch is a standard used in most remote controls. Jaycar and Altronics sell them.
